G. J THOMAS UNIVERSAL JOINT m: r00 GEOEGf J. OM95 A TTOR/VEY grooves 22 register so as to form c consider able space for iubricont. This construction is particularly advantageous for the rec-soc that the lubricant stored in the space formed by i'he grooves 22 can pass in any direction io the various truimioiis or hearing pins and their seats or recesses 12. Furthermore, the lubricant bein stored in the annuicr space 22 formed by t io junction of the members 10 and 11 cannot be thrown out by centrifugal force Wiihooi passing through the seats containing the trunniocs or hearing pins, 3 and -."i wl'ierccs if the space formed Icy-(he chain: fcrcd ed' es 14. is rciied on entirely 0 contain the lubricant, centrifugal force has a. iced cncy to keep the. lubricant from Working into the bearings during the rotation of the joint members.

The members 10 and 11 airs hold together by a clamping bond 16. As shown in Fig. 7, the bond is formed with H. coiiar 17, which engages the shoulder 13 on one of tho members, for example if), when pioced in posi tion Within the band. En. chc assembly Fig. 1, I have chowii bearing bushings 18 over each of the pins 3- cnd i, and these bushings rest in. the recesses ,2, but in 10 co 1 .13. the :Corm shown or buehiiigc are shown. Fig. e is used a; ivosi soitebie' packing moicriei so "which io pieced-e. cup room washer E prcif of steel. The i. iclrcecs oi? the washer such. during the assembly it viii be moressed cbout' oiie had? of ice "oormol eizesc that in operation ii; iviii exclude rt and water from the joini: bccringe, at

2%; mode ti o some iime it will retain the lubricant.

While ibis coneiroction provides iubricciaioii and protection ioihe joint peris, it further serves to "take up oii wear and prevents rec tie .bsfivreeii 'iho foint members.

iiftec tho joint members 1 and 2 hove been icd in position, the other member 11, which isproferobljr e duplicate of 10, is picced in position and the edge 19 of the clamping bond is spam over the shoulder 18 clearly indicated in Fig. 1, thereby coiripiebiogzihe assembly of the joint The oping bond 16 is provided with. a projeciion :ZDWhich may have pipe threads chereijc in order chartv e lubricating cup Ifia be attached thereto, in order to pass lubricom; to the peripheral sacc 21 or to the annular grooves 22 or to 0th when used.

The manner of adding lubricant to the space 521 or grooves 22 may take any other desired form than that above described, iike-. ivisc certain of the other details of my in" vencion may be varied Without deportin from the spirit of the same or the scope oi the appended claims.

Ewing thus 1 aim is:

4. In o device for enclosing and lubricating the bearing trunnionsof o universal joint, a. pair of rings'for engagiu the irun- :cions, at least one of said rings eing pr0- vided in its face with an ommizir lubricating between said trunnion bearings, and a, bond encircling the rings and having integral edges turned over ihe sides of the rings 'or clamping scid rings in operative position with respect to idle,

trunnions and retaining the lubricant be twcenjhc rings.

5.11m device of the class described, a. pair of joint members each having bearing crow n1ons,'mcans for enclosing and lubricating the trunnions comprising a pair of riiigs for engaging the trunnioiis, :1. band eiicirciing the rings and having its edges turned over the edges of the rim-is for clamping the abutting? ice faces of said rings in operative position with respect; to the trunnions, and means for lubricating said trunnions including a groove for lubricant in the face of at least one of saidrings, so that centrifugal force will tend to force the lubricant in the groove into the trunnion bearings as described.

6. In a device of the class described, a pair of joint members each having bearing trunnions, a pair of rings for engaging the trunnions, means for lubricating said trunnions including a groove for lubricant in the face of at least one of said rings, so that centrifugal force will tend to force the lubricant in the groove into the trunnion bearings, a band encircling; the rings having its edges turned over "the sides of the rings for covering the joint between the rings and clamping them in operative position with relation to the trunnions.

7. In a device of the class described, a

pair of joint members each having bearing trunnions, members for engaging said trunnions, and a band encircling said members and having its'edges turned over the sides of said members for clamping said members in operative position with respect to the trun nions and having a drawn out seat for a lubricant fitting opposite one of the trunnions.

8. In a device 01'' the class described, a pair of joint members each having bearing trunnions, members for engaging said trunnions, and a band encircling said members and having its edges turned over he sides 01. said members for clamping said neinbers in operative position with respect to the trunnions, and means fior luh icati-g said trunnions including a gro ve formed by safe members.
